ABSTRACT:
A structural composite material is provided. The material comprises a thermoplastic layer, a layer of fibrous material spaced from the thermoplastic layer and a foam core disposed in the space between the layers. A resin impregnates and holds the layer of fibrous material together to form a fiber-reinforced resin structure. The foam core and the fiber-reinforced resin structure are integrally formed from a core material capable of having both a foamed character and a resinous character. A process for manufacturing the composite and a boat structure formed from the material are also provided.
